CMP Zero Paint what colors?
 

I have one of the flat painted versions of the CMP Zero and since this is my first painted plane I want paint to patch any scuffs or repairs I may need to make, what colors are on this plane?

I have tried to match the gray on the bottom at the hobby shop but I everything seems to be either to dark or light so any ideas?

Also I am looking for what the color is for the green on the top of the plane.
